Answer:
shoe store $7.80/hour
telemarketer: $6.90/hour
Step-by-step explanation:
Let s = hourly salary at the shoe store.
Let t = hourly salary as a telemarketer.
14s + 19t = 240.3
19s + 22t = 300
Multiply both sides of the first equation by 19. Multiply both sides of the second equation by -14. Then add them.
266s + 361t = 4565.7
(+) -266s - 308t = -4200
----------------------------------------
53t = 365.7
t = 6.9
Substitute 6.9 for t in the first equation and solve for s.
14s + 19(6.9) = 240.3
14s + 131.1 = 240.3
14s = 109.2
s = 7.8
Answer:
shoe store $7.80/hour
telemarketer: $6.90/hour
Step-by-step explanation:
5z, 5x and 5y are all unlike terms.
If there was something like <em><u>5z</u></em> + 5x <em><u>-</u></em><em><u> </u></em><em><u>3z</u></em> + 5y, then both 5z and -3z have something in common and so therefore are said to be like terms.
Hope my description helps.
Good night.
